Well I'm trying to get a wild Poke, not Rayquaza.
So let's say I set my target time for 11:30:15. I change my DS clock to 11:29:00 completely. When I set the time, I also set the first timer on Pikatimer to 60 seconds (and my second timer is 15 seconds). Right when I set the clock, I also press Start on Pikatimer. I wait until a minute passes by, then when the first timer hits 0, I launch the game. I get to the continue screen and hit continue right when the second timer reaches 0. I search for a Pokemon, catch it, and put the stats on RNGReporter (also I put in the time I entered the game). After I set up the stats and everything in the "Seed to Stats" tab, I click "Find", and it usually comes up with one or two matches, but both of the matches either say 495 delay and 1 second or 650 delay and 22 seconds.
What am I doing wrong?
